Abstract: Biofuels are being promoted as a low-carbon alternative to fossil fuels as they could help to reduce greenhouse gas (GHG) emissions and the related climate change impact from transport. However, there are also concerns that their wider deployment could lead to unintended environmental consequences. Rising energy prices, geopolitics and concerns over the impact of greenhouse gas emissions on climate change are increasing the demand for biofuel production. The aim of this research is to review and analyse the latest available evidence to provide a greater clarity and understanding of the environmental impacts of different biofuels and also discuss the impacts of biofuels on climate change, water use, and land use, also the life cycle assessment is studied. A Survey in Biofuel Manufacturing plants is done. Policies should promote the development of sustainable biofuel programs that have very low inputs of fossil fuels and chemicals that rely on rainfall or abundant groundwater, and that use land with little or no economic or ecological value in alternative uses. The recent historic use of biofuels in the context of Government policy developments will be presented.
